Abstract: ABSTRACT OF THE DISCLOSURE     An I/O controller functions to provide management of, control of, while functioning as two "virtual" data link processors for at least two separate types of peripheral terminal units, thus enabling data transfers between a host computer and any selected one of the peripheral terminal units.  A commonly shared logic interface, common to both virtual controllers, is selected for use by a Request-Program Array Logic unit which arbitrates the utilization of the common logic by one of two virtual controllers at any given time.  A first and second status latch is provided in the common front end interface of the I/O controller whereby each status latch provides status signals to the main host computer system of the state of any one of two virtual controllers which share common interface to a host computer.  At the particular time that the host is addressing one of the virtual controllers (for the purpose of initializing communications with that controller) via its status latch register, a path is provided to the I/O microprocessor in the controller such that microprocessor access to that status latch is temporarily inhibited in order to maintain stable status signals for the interrogating host computer.

Abstract: S-80/?WT-1 08/1?6 ABSTRACT OF THE DISCLOSURE                  A papermaker's felt having an elongated base fabric, at least one batt layer, and means to interconnect the opposite longitudinal ends of the base fabric to make an endless felt.  The endless felt is made by providing seaming loops on opposite longitudinal ends of the base fabric and bringing the loops into interdigitated engagement on the paper making machine; introducing a core element into the common bight of said loops to connect them; and finally needling the batt layer so that the abutting ends thereof (which abut each other at right angles to the longitudinal direction and obliquely to the thickness direction) are engaged without any opening between them.  Marking the paper on the felt is avoided by specially preparing the felt before putting it on the machine, by positioning said seaming loops in longitudinally spaced-apart relationship and inserting shape-retaining wires into the bights of said loops; and needling a batt layer on at least one side of the fabric and between said spaced-apart loops to make the batt layer endless; cutting said batt layer widthwise adjacent the loops of the fabric into flat form; removing the shape-retaining wires from the bights of the seaming loops at the opposite ends and temporarily connecting to loops and cutting away the extra fibrous batt so that the cut ends of the batt may abut one another obliquely to the thickness direction of the batt.

Abstract: INVENTION: DEVICE FOR DEMODULATING            A SPREAD SPECTRUM SIGNAL INVENTOR:  STEVEN MESSENGER                   ABSTRACT OF THE DISCLOSURE Circuitry for receiving and demodulating a spread spectrum signal integrates signal acquisition and tracking functions and also accommodates signal drift. Two data decoding signals are generated which correspond to the pseudo noise code used to modulate the received signal and which are phase-shifted by a half-chip interval. Two correlators use the decoding signals to demodulate the received signal, both during acquisition and tracking, producing two data signals. A summer combines the two data signals to produce a signal whose strength is less dependent on the degree of synchronization of each data decoding signal with the received signal. Tracking error circuitry periodically compares the two demodulated data signals and incrementally phase shifts the two data decoding signals, the magnitude of the increment being one-quarter chip and the polarity being selected to strengthen the weaker of the two data signals. This causes the circuitry to track the received signal despite gradual signal drift. A bank of correlators also demodulate the received signal using test decoding signals having different phase angles. The phase angles of the test decoding signals are periodically adjusted to locate stronger signals. Control circuitry constantly compares the strength of the demodulated test signals and of the two data signals and adjusts the phase of the two data decoding signals to correspond to that phase producing the strongest demodulated signal.

Abstract: ABSTRACT: Multi-stage transmitter aerial coupling device.     Coupling a plurality of transmitters operating with different carrier frequencies to a single aerial is often effected by multiplexing the output signals by means of band-pass filters in the output frequency band. The band-pass filters have one end connected to a start network and from there to the aerial via an aerial transmission line, and the other end to the transmitters via circulators.          For an optimal use of the available frequency band, for making less stringent requirements on the band-pass filters and for providing a dynamic channel assignment feature, the transmitter coupler according to the invention has a first stage in the form of a digital coupler and a second stage in which multiplexing is effected, using band pass filters. The transmitter output signals are combined in the digital coupler, in the pre-group phase, by digital signal processing, preferably using the GTFM method. In the second stage the output signals of the parallel-arranged digital coupler are subjected to a digital-to-analog conversion in the group-phase and to frequency conversion.

Abstract: Abstract of the Disclosure A sensor (24) having a metal shell (30) joined to a sleeve (96) to locate a heater (92) in a thimble of an electrolyte member (72).  A sealed joint is produced between the sleeve (96) and metal shell (30) to define a sealed reference chamber (118).  A porous filter (112) in the sleeve (96) prevents water in environmental air from entering the reference chamber (118).  Leads 106' and 106" which pass through the porous filter (112) are con-nected to terminal (164 and 164').  Terminals (164 and 164') located in a terminal member (120) position a heater (92) within chamber (118) and the electrolyte member (72).  Leads (106 and 106n) which pass through the porous filter are connected to contact rings (142 and 144).  Contact rings (142 and 144) are connected to an external and internal coating (80 and 82) on the elec-trolyte member (72).  In response to a signal from a controller (26) electrical current is supplied to the heater (92) to maintain the temperature in chamber (118) above present limits such that changes in the ion con-duction through the electrolyte member (72) is accurately measured.  The changes result from a difference in the oxygen content of air in the reference chamber (118) as compared with oxygen in an exhaust gas supplied to the external surface (80).

The valve device comprises a sensor device 53, 56 designed to sense the gas speed and the direction of the gas flow in the gas duct in the apparatus, and a power device 61, designed to open the valve when the gas speed in a predetermined direction exceeds a certain value. The sensor device comprises a duct 53 with a constriction 56 and inlets to side ducts 57, 58 located on both sides of the constriction. The power device 61 is designed to adjust the valve 64, 65 to its various positions by utilising the higher pressure which, depending on the direction and speed of flow of the gas, occurs on the inlet side of the constriction, compared to the lower pressure downstream of the constriction. The power device is formed by two chambers 59, 60, which are connected to the side ducts 57, 58 and which are separated by a moveable element, such as a membrane 63, to which the valve is connected.
